The premise of this one isn’t particularly special, but in execution, Avril is a really fun protagonist to follow. She plays the kind of dense female lead archetype, but it doesn’t get old because of her dedication to acting like a villainess. She’s imitating her actual villainess half sister, but she’s so incredibly bad at it and it wraps right back around to being endearing.
